LOCK.'

Specification of Letters Patent.

Patented Dec. 29, 1914.

Application vfiled June 9, v219311. Serial liTo. 632,114.

To aZZ whom it may concern Be it known that I, FRANK SoLEY, a citizen of the United States, residing at lhilade'lphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Locks, of which. thefollowing is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification. l

My invention relates to that-class of locks in which the direct controlling means for the bolt .is a stump mounted or connected with a ,stump carrier. V

The purpose of my invention is toprovide such locks of such construction as to require a specific key adapted for each lock land with an varrangement whereby a series of such locks may be controlled by a master key. l

Generally speaking, my invention comprises a bolt, a stump and stump carrier, and tumblers, the tumblers having notches adapted to the stump and which when the notches in the tumblers are brought into alinement, allow the movement of the bolt to release the lock.

In my arrangement, the tumblers can be operated by the key to bring first the notches in the tumblers into alinenient with the stump and then'the further action of the key moves the stump allowing the bolt to be withdrawn. The arrangement may also be such that the stump is moved simultaneously with the tumblers to elevate the stump, the desired extent until it alines with a notch in tumblers which it enters, allowing the bolt to be moved.

I will now describe the embodiment of 40 my invention shown in the drawings, and then specifically point out the invention in the claims.

In the drawings: Figure l is a front view of a shackle lock embodying my invention with case opened showing lock in closed position. Fig. 2 is a similar View with lock in open position. Fig. 3 is a section on line 3 3, Fig. l. Fig. 4 is a view of regular key for my improved lock. Fig. 4b is a view of a master key for my improved lock. Fig. 5 is a view similar to Fig. l. Fig. 6 is a view similar to Fig. 2 of a bolt or latch lock. Fig. 7 is a section on lines 7 7, Fig. 5. Speaking first oi' Figs. 1 4, which show 5 a shackle lock. a is the shackle, b the holding dog. This dog is held from movement by means of the projection c on the bolt d against which a projection e on the dog b rests. The movement of the bolt c! to release 'is on the stump carrierp. The stump normally strikes the solid portion of the tumblers. In this case the stump and stump carrier are' pivoted so as to have only a vertical movement in the arc oi' a circle. The bolt d has a linear movement, being slidable on the guide w. The tumblers /i are' pivotally mounted on a stud j on the bolt and thereby have both a movement in the arc of a circle and a linear movement.v The tumblers have the under-cut portion z'. The outer surfaces of these tumblers have notches 7c and o. The outer surface of the bolt has corresponding notches similarly lettered. The depth of the grooves in the key causes the tumblers to have a proper povement to aline the notches in the tumers.

The lock may be operated in two ways. A key Z (see Fig. 4ta) may be provided which need not act upon the stump carrier but may act only upon the tumblers and their coacting bolt. Under the action of this key, the tumblers are moved in the arc of a circle until the notches 7c in the tumblers aline with each other and with the notch r: in the bolt and with the stump. The cut away portions of the tumblers enable the projection mon the key to pass under the tumblers and strike the bolt, moving it laterally when the stump is thus alined with the notches in the tumblers, thereby releasing the dog and the shackle opens. (See Fig. 2). On the other hand, a key n may be provided (see Fig. 4b) having the projecting portion p which strikes the stump carrier simultaneously with the action of the key upon the tumblers. This causes a movement of the tumblers in the arc of a circle, arranging a set of notches o therein in alinement with each other and with the notch 0 in the bolt. The notches are thus arranged to receive the stump simultaneously with the movement of the stump to aline with said notches. These movements are so timed that the said notches aline and are opposite to the stump at the time the stump is elevated opposite to the notches, and just as the projecting portion 7) of the key n strikes the bolt moving it laterally.
